Flood levels from Hurricane Floyd exceeded those from Hurricane Fran, which occurred in September 1996.Preliminary assessments indicate that flood levels in much of the Tar River Basin were at the 500-year recurrence interval. (500-year flood flow has a 0.2-percent chance of being equalled or exceeded during any given year at a particular location.)

As the Labor Day weekend approaches, scientists from the U.S. Geological Survey are heading for the beach. They are not packing the usual lounge chairs, cooler, and snorkel masks; their beach gear will include sidescan sonar equipment, a data acquisition system, sampler, and a navigation system.

Concentrations of phosphorus and nitrogen have generally declined since 1980 in streams draining into the Albemarle and Pamlico Sounds in North Carolina but remain high enough to cause water-quality problems in the Neuse and Tar-Pamlico Rivers, according to the results of a 5-year investigation by the U.S. Geological Survey (USGS).

From coastal erosion to measuring the storm surge and flooding as well as providing maps of affected areas, the U.S. Geological Survey is gearing up to provide information on Hurricane Fran as the storm develops, including real-time data, from its offices in Florida, Georgia, South Carolina, North Carolina, Virginia, Maryland, Delaware, Pennsylvania, New Jersey and New York.
